For palaeontologists, DNA is infuriatingly fragile. Its lengthy chains start to interrupt aside shortly after loss of life, destroying invaluable details about the deceased guardian organism. In contrast to bones, footprints and even faecal matter, which might comfortably survive—in fossilised type—for hundreds of thousands of years, DNA not often lasts way more than 100. In current a long time scientists have found that some exceptionally well-preserved our bodies do nonetheless have readable fragments of genetic code a whole bunch of hundreds of years after loss of life. However these have been tiny scraps. They lack a lot of the precious info that an intact genome supplies.
